Description
Technical Field
The application belongs to the field of thickened oil exploitation, and particularly relates to equipment for thickened oil exploitation by utilizing energy-gathering pulse and a use method thereof.
Background
The thick oil refers to high-viscosity heavy crude oil with viscosity of more than 50 mPa/s under stratum conditions or viscosity of l 000-10000 mPa/s of de-aerated crude oil at reservoir temperature. In oil exploitation in oil fields, thick oil has special high viscosity and high freezing point characteristics, and some technical problems are encountered in various aspects of development and application. In terms of recovery technology, gum, asphaltenes and long chain paraffins cause poor mobility of crude oil in reservoirs and wellbores, requiring implementation of high input tertiary oil recovery processes. The transportation of highly viscous, highly viscous oils must employ more powerful pumping equipment and require heating of the transportation system or dilution of the crude oil in order to achieve reasonable pumping capacity. According to the data report, the reserve of thickened oil in China is seventh in the world, and 9 large and medium-sized oil-containing basins and a plurality of thickened oil reservoir blocks are found so far. In the development process of the petroleum industry, lighter crude oil which is easier to produce is firstly produced in various countries in the world. Foreign countries with large oil reserves have high cost and risk of thick oil exploitation because of abundant resources, and the thick oil exploitation is not listed in the agenda. Once the thick oil well is drilled, the method of well sealing is generally adopted except for partially meeting the requirement of industrial production, and the thick oil well is temporarily put aside and is not mined.
With the progressive decrease in lighter crude oil resources, some heavy oils that are more difficult to produce have to be started to be produced, and thus the share of heavy oils in world oil production is increasing. In recent years, china has accelerated the development of thick oil, and the yield of thick oil at present is about one tenth of the annual yield of petroleum in China. The prior thinking of improving the yield of the heavy oil reservoir is mainly to reduce the viscosity of the heavy oil, improve the permeability of the reservoir and increase the production pressure difference. The main mature technologies are steam injection thermal recovery, in-situ combustion, hot water and chemical huff and puff or sand carrying cold recovery and the like. The main problems of the methods are low extraction rate, huge energy consumption cost, environmental protection and the like. In either way, the biggest problem faced by heavy oil recovery is the problem of recovery cost. This problem is a major difficulty in current heavy oil recovery, especially in the case of large variations in current international oil prices.

Detailed Description
Embodiments of the application are described in detail below with reference to the attached drawings, but the application can be implemented in a number of different ways, which are defined and covered by the claims.
To achieve the above object, the present application provides an apparatus for heavy oil recovery using energy concentrating pulses, referring to fig. 1, comprising an uphole device and a downhole device, the uphole device comprising a controller 2, a power source 1 and an energy concentrating pulse generator 3, the downhole device comprising an energy concentrating pulse releasing electrode 4, the power source 1 being connected to the controller 2 and the energy concentrating pulse generator 3, respectively, the energy concentrating pulse generator 3 being connected to the energy concentrating pulse releasing electrode 4 by a cable, the controller 2 being connected to the energy concentrating pulse generator 3 by an optical fiber to control the energy concentrating pulse generator 3 to generate a shock wave for the energy concentrating pulse releasing electrode 4 to emit.
The device comprises a power supply 1, a controller 2 and an energy gathering pulse generator 3, wherein high energy and high voltage generated by the power supply 1 is transmitted to energy gathering pulse equipment through a cable, and the energy gathering pulse generator 3 gathers energy and then releases the energy through an energy gathering pulse releasing electrode 4. Under the action of high-pressure electric field, the energy-accumulating pulse releasing electrode 4 in thick oil emits electrons and ionizes liquid molecules near the electrode. Electrons emitted by the electrodes and ionized electrons in the liquid are accelerated to ionize more electrons by a strong electric field between the electrodes. A plasma channel is formed in the region where the liquid molecules are ionized. As the ionization region expands, a discharge channel is formed between the electrodes, and the liquid breaks down. After the discharge channel is generated, a discharge current of tens of kiloamperes is generated due to the small discharge resistance. The discharge current heats the liquid around the channel, causing the liquid to vaporize and expand rapidly outward. The rapidly expanding air cavity generates a strong shock wave in the aqueous medium. The shock wave acts on the surrounding medium in the form of impulse or shock pressure according to the discharge current and the discharge time. The method is equivalent to using fluid pulse to impact the oil layer to loosen the oil layer so as to improve the petroleum extraction rate. The shock wave generated by the energy-gathering pulse can generate thousands of times of gravity acceleration, the discharge current excites a transient magnetic field of upper Mo Gaosi around the discharge channel, the changed magnetic field establishes an electric field and thousands of amperes of current in the conductive fluid in the thickened oil, and the strong magnetic field has strong polarization effect on the oil layer medium. The energy-collecting pulse generates plasma (plasma pulse) and acts on the thick oil molecular chain. The plasma pulse technology selects basic hydrocarbon molecules, breaks molecular chains, and makes the hydrocarbon molecules smaller so as to improve the permeability of thick oil through small pores. The controller 2 can adjust the shape, wavelength and amplitude of the energy-gathering pulse, and can be suitable for various conditions of different viscosity of the thickened oil.
Preferably, the downhole device further comprises an energy storage device 5, the energy storage device 5 is located between the energy accumulating pulse generator 3 and the energy accumulating pulse releasing electrode 4 to store energy generated by the energy accumulating pulse generator 3 and transmit the stored energy to the energy accumulating pulse releasing electrode 4 for releasing, and the energy storage device 5 is further connected with the controller 2 through an optical fiber.
Since the thickened oil is located deeper below the bottom layer, a large portion of the energy generated by the energy concentrating pulse generator 3 is consumed by the cable connecting the energy concentrating pulse generator 3 and the energy concentrating pulse discharge electrode 4, and the effect of the energy reaching the energy concentrating pulse discharge electrode 4 on softening the thickened oil may be reduced. Therefore, an energy storage device 5 is arranged between the energy collecting pulse generator 3 and the energy collecting pulse releasing electrode 4, so that energy is firstly collected in the energy storage device 5 and then released through the energy collecting pulse releasing electrode 4. Thereby improving the softening rate of the thickened oil and the exploitation efficiency. The energy accumulator 5 is controlled by the on-well controller 2, can observe the energy storage state in real time, and determines the energy release time and the energy release times according to the flowing condition of the thick oil
Preferably, the energy concentrating pulse generator 3 is a Marx generator.

When a certain margin is considered, the number of stages is set to 3-10, so that the capacitance of each stage is 4.8uF. Therefore, the isolation inductor, the main capacitor and the switch of the inductance-isolation type Marx generator all need to be specially designed.

where N is the number of turns, D is the diameter of the coil, and Φ is the value that varies with A/D, where A is the length of the coil. Here, d=154 mm, a=240 mm. Then it can be looked up from the table: Φ=4.91, substituting the upper value, the relationship between inductance and number of turns can be obtained, as shown in fig. 2. N is taken as 15 turns. Meanwhile, let the diameter of the wire be d, then the inductance first correction term:
wherein:meanwhile, the second correction term is:
it is a value related to the number of turns, N being 15, j= -0.2857.
In the calculation, if the number of turns N is 15 and the wire diameter d is 1.0mm, the inductance can be obtained:
and (3) selecting a main capacitor:

The volume of the relevant capacitor is specially tailored.
The design of the switch:

The I-type electrode is a field enhanced electrode, the first two stages adopt the field enhanced electrode, the preferential conduction of the first two stages of Marx can be ensured, and the rest 10 stages adopt II-type uniform electrodes, so that the preferential conduction can be effectively avoided, and the Marx can not effectively establish discharge. For the determination of the main gap, the breakdown field intensity needs to be estimated, and the breakdown relation of air or nitrogen under static voltage is as follows:
wherein p is the inflation pressure (0.1 MPa) of the switch, d eff Is the effective distance (cm) of the electrode, and f is the field strength enhancement factor. For a flat electrode: d, d eff /d=1.0, f=1.0. Where d is the distance (cm) between the two electrodes, thus the breakdown voltage U br ＝E b Xd (kV) is available.
Preferably, the power supply 1 is an AC/DC power supply, the output power of the AC/DC power supply is 60KW, and the output voltage is 30KV.
According to the underground production requirement, the output power of the power supply 1 is 60KW, and the output voltage is 30KV.
